Yes, there is a thing that almost guarantees things in the future will materialize, it’s called a contract. People and businesses have been dealing in futures for centuries. For instance, Italian banks have special vaults for Parmigiano Reggiano taken as collateral. If some of their customers didn’t have access to these tools they probably would’ve gone out of business long ago, and we’d all have lost access to great cheese.

They’re just tools, as such expected to be held the wrong way by some people.

PS: I had a lot of fun developing an accounting system for a client that needed to solve exactly this problem :)
